The young girl the protagonist picked up from the slums, intending to teach her alchemy so she could support him, turned out to be an incredible genius, quickly surpassing the alchemy skills of her master.

However, for various reasons, the protagonist, unable to shed his persona as the "Great Master," achieves the affluent life he idealized, but at the cost of enduring some inexplicable mental strain on a daily basis.

This is the story of a "Great" Master who is a freeloading mediocrity, and a genius girl who adores such a master.
